To ril/7 whom 'it may conceive: y

Be it known that I, FRANois l/Ven'rnn BOURGOIN, a citizen. oi the United. States, and a resident of the city of St. Louis, in the State oi Missouri, have invented an lmprovement in Crispette-M-achines, of which the following is a specification.

My invention is` an improvemen-tin crisp ette machines, and has for its object topro"- vide a machine of the character specified, wherein a plurality 0i? incl/ds isk provided and a plunger cooperating therewith, the molds being mounted in a carriage to be moved inl alternationV beneath; the plunger, and wherein `an ejecting means is provided controlled by the movement of theplunger for ejecting the formed crispettes, and whereiny the movement of the plunger ralso controls the moving of `the carriage.

Figure if is a side View yof the improved machine.

Fig. 2 is a similar View with the partsin another position and: with parts in section.

Figs. 3 and 4 aresections on the lines 3-3 and 4 4 of Fig. l. p

Fig. 5 isv a front view of the'- pawl and ratchet connection. v y

Fig. 6 is a section on the' line (5;6 of Fig. 5.

In the present embodiment of the inve tion a suitable table l` isl` provided, and a portion of the top of the table is cutaway frame. The iframe at the upperedge of the opening is rabloetedl to receive a `plate 2", and beneath this plate is arranged `a casing 3 and beneath the casing is arranged a suit able heaterll` forheating the air in thecasing. lllhe casing has a cold air inlet 5, and a discharge outlet 6, which communicates with a suitable chute 7 at the under side thereot for delivering the crispette material to the molds to be described.

Above' the table is mounted a carriage 8, the carriage beingl movable longitudinally oi? the table by mechanism to` be'flater described, and the carriage travels in guides 9" arrai'iged at opposite sides of the table and supported by brackets 110 connected with the table. The space between the guides and the table top `is inclosed by a species of casing il, and? the moldsk i12 are supported by mechanism to be later described, tobring the molds in alternation beneath a plunger 1ndicated at lit and at the opposite sides of the plunger discharging chutes 15 lead? from vopenings in the table top, the said chutes being in position such that the mold' not be* neath the plunger will register withonev` oil the chutes.

Referring to Fig. 2 it will bessen that the mold at the right registers with the chute at the' right, and it will be evident that when the mold at the right is brought into register with the plunger, the mold at the left willi be in register with the chute I5 at the le'nl);

The plunger la is a hollow cylindricalV casing adapted to contain melted butter, and

the said casing is of a size to fit within the molds. A Yfeed casing ,L6 encircles the plunger, andv the mold isf slidably mounted with respect to said casing and the chute 7 before-mentioned delivers to the said casing, an opening i7 being provided in the casing at the bottom of the chute. When they plunger is raised with respect to the casing 1G, in amanner to be presently described?, a portiony oi' pop corny may be fed through the opening I7 into the mold' l2 which isbe low the plunger. When now the plunger descends, it will be evident that the pop corn will be compressed into a crispette within the mold, being held at one end by the table top Q and at the other by theY bottom of the mold. The melted butter which may pass throughy the openings 14a inthe plunger wall and in the bottom thereof will thor.

oughly lubricate the mold and casing 16, so that the plunger will not stick to the pop corn or to the mold. Vhen the plunger is again titted out ot the mold, the table' is moved a sulhcient distance to bring the other mold in place beneath the plunger, and to bring that mold which carries the crispette over a discharge chute 15.

Ejecting mechanism is provided, controlled by the movement of the plunger, the said mechanism comprising rods 18 having heads at their lower ends, the rods moving" through guides 19 arranged above the carriage and connected with the guides 9. The plunger has threaded into the upper end thereof a plug 20, and a cross head 21 is piv oted to this plug. The ends of the cross head are'pivoted to the rods 18, and a pair of links 22 and 23 connect the cross head with the operating lever 24 for the plunger. The lever is pivoted at one end to an upstanding brack-et arm 25 from the table, the said arm being braced against the table by an inclined brace 26, and it will be evident that when the lever is lifted, as indicated by the arrow in Fig. 1, the plunger 14, the head 21, and the rods 18 will also be lifted. As soon as the plunger and the ejecting rods have cleared the carriage, the carriage is moved, and the movement of the plunger controls the moving of the carriage.

An 4elbow lever consisting of portions 27 and 28 is pivoted at the pivotal connection of the lever 24 with the bracket 25, and the portion 27 of the said lever has a toothed segment 29, which engages a pinion 30 on a shaft 31. This shaft is held in a bearing on the bracket 25, and a ratchet wheel 32 is arranged on the shaft adjacent to the pinion, the ratchet wheel being secured to the pinion. A disk 33 is mounted on the shaft outside of the ratchet wheel, and this disk has a marginal flange inclosing the ratchet wheel. vPawls 34 ar-e pivoted to the disk, and the said pawls are spring pressed toward the ratchet wheel. When the pinion is rotated in one direction the disk 33 will be rotated while when the pinion is rotated in the opposite direction the pawls will slip idly over the ratchet wheel. A pitman 35 connects the disk with the carriage in such manner that when the disk is rotated the carriage will be reciprocated.

The portion 28 of the elbow lever extends above the lever 24, and the said portion has a lateral lug 36 which overlies the lever 24 and is adapted to be engaged thereby at the moment when the plunger 14 clears the carriage. A guide loop v3'? is connected with the lever and engages over the arm 28 of the elbow lever, and it will be evident that when the lever engages the lug 36 and is move'da trifle farther upward, the pinion 30 will kbe rotated Ato cause the table to be moved from the-position shown in Fig. 2 to a position such that the mold at the left will register with the chute 15 at the left, and with the ejector 18 at the left. Vhen now the plunger is moved downward to form a crispette in the mold at the right, the crispette in the mold at the left will be ejected, and the ejector 18 at the left will move in the guide casing 13 at the left.

The feed casing 16 is anchored to the carriage during the movement of the plunger into the mold, by means of a gravity lock indicated at 38, the said lock being in the form of a rod mounted to move in guide lugs 39 on the casing 16. lThe lower end of the rod is adapted to engage openings 40 in the carriage at the respective molds, `the said opening being so positioned that when the rod engages the same the casing will be directly above a plunger.

A latch 41 is pivoted within a recess 41 in the plunger, and this latch extends through a vertical slot 1Ga in the feed casing 16 and is adapted to engage a lug 42 on the locking rod. The lower end of the latch 41 is normally held in extended position by a spring which encircles the pivot pin of the latch. It will be noticed that just above the catch of the latch is a cam shaped portion,

which is adapted to engage the upper end of the slot in the feed casing 16 in which the latch moves, to release the latch. Vhen the plunger rises, the latch engages the lug 42, and lifts the latch bar. The plunger, by this time, is out of the mold, and a further slight raise lifts the latch bar 38 out of the opening 40. A further movement of the plunger causes the cam shaped portion of the latch to engage the upper end of the slot in the feed casing and the latch bar is released, dropping on tothe carriage and engaging the other opening 40 when the parts are in proper position. The latch 41 is so arranged, that it will not engage the lug 42, until the moment before the lower end of the plunger clears the top of the mold. The slight farther movement of the plunger will lift the latch to free the carriage. The farther upward movement of the lever 24 to operate the elbow 27-28 lifts the plunger far enough to permit a new supply of material to pass through the opening 17. The casing 16 is connected with the guides 19, by means of braces 44.

In operation, with the parts in the position of Fig. 2, the plunger is abo-ut to descend into the mold. During the descent of the plunger the pawls 34 slip idly over the ratchet wheel 32. A crspette is formed, and the plunger is again lifted into the position of Fig. 2. At this moment both plunger and ejector are clear of the carriage, and the lever 24 engages the elbow lever 27-28, and the table is reciprocated, to move the mold at the left into position beneath the ejector at the left, and to move the mold at the right into position beneath the plunger. At the same time a charge of pop corn is fed. into the mold. The plunger moves downward, and before it begins to move into the mold los mit@

the latch 38 is released to lock the carriage to 'the casing 1G. As the plunger moves into 'the mold to (.:ompress the charge of pop corn, 'the charge already compressed in the other mold` is ejected. The heater -lretains the butter in the plunger in melted condition, and .retains the candy on the pop corn in a condition soft enough to insure the proper fori'nution of the crispette.

It will be understood that the downward movement of the operating lever returns the elbow lever 27-28 to original position, that is to the position shown in liig. l, because of the loop 87.
